Thank you @tanishbahir7055 for your insights about the thumbnail improvement, etc. While revising the thumbnail, I identified a mistake that pushed me to re-upload the updated video.
As I unlisted the old video, the community post's comment is disabled so I decided to remove that community post to avoid confusion: if I am asking for advice, why would I disable comment. However, I want to give you credit in this comment. Thanks bro.
